摘要:报道了钯催化芳基和杂芳基卤化物与新型硼酸化剂四(二甲氨基)二硼 [(Me 2 N) 2 B-b(Nme 2) 2] 的硼化反应.该方法是对先前报道的利用双硼酸 (Bba) 的方法的补充,因为某些底物在一组优化的反应条件下比另一组表现更好.由于四(二甲氨基)二硼是 Bba 和双(频哪醇)二硼(b 2 Pin 2)的合成前体,因此新方法代表了当前硼化方法的原子经济性和效率更高的方法.

摘要:The present invention discloses a targeted synthesis method for the synthesis of asymmetric monoesters and/or symmetrical diesters of citric acid through acidic esterification by using boric acid or a boronic acid as a catalyst. The boric/boronic acid simultaneously acts as a catalyst, as well as a 'protecting group' for the tertiary carboxylic acid, and therefore specifically only the asymmetric monoesters or symmetrical diesters are created.
